form_field(3X) Library calls form_field(3X)
form_field - make and break connections between fields and forms
#include <form.h>
int set_form_fields(FORM *form, FIELD **fields);
FIELD **form_fields(const FORM *form);
int field_count(const FORM *form);
int move_field(FIELD *field, int frow, int fcol);
The function set_form_fields changes the field pointer array of
the given form. The array must be terminated by a NULL.
The function form_fields returns the field array of the given
form.
The function field_count returns the count of fields in form.
The function move_field moves the given field (which must be
disconnected) to a specified location on the screen.
The function form_fields returns a pointer (which may be NULL).
It does not set errno.
The function field_count returns ERR if the form parameter is
NULL.
The functions set_form_fields and move_field return one of the
following codes on error:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_CONNECTED
The field is already connected to a form.
E_POSTED
The form is already posted.
E_SYSTEM_ERROR
System error occurred (see errno(3)).
These routines emulate the System V forms library. They were not
supported on Version 7 or BSD versions.
The SVr4 forms library documentation specifies the field_count
error value as -1 (which is the value of ERR).
